Just to inform you guys that I did this release yesterday.
It fixes a number of bugs and reintroduces Seam pageflow. As you already know, the complete jPDL language is supported now.
You can help us by trying it and providing us with your valuable comments and remarks. Download the plugin here: http://labs.jboss.com/jbossjbpm/downloads.
Forgot to mention that I wrote a blog entry yesterday in which I highlight how to configure tasks using the new GPD. If you're interested have a look at it : http://koentsje.blogspot.com/2007/07/configuring-tasks-in-jbpm-jpdl.html
